Create VM ClassStat agent and common bundles This commit extracts VM ClassStat data collection from SystemBackend and related classes into a vm-classstat-agent bundle. It also moves the VmClassStatDAO from common-core into a vm-classstat-common bundle that registers the DAO once Storage is available. This also removes the DAO from DAOFactory. This commit also simplifies what's left of JvmStatHostListener since it only handles collecting VmInfo data, and rewrites the corresponding test to better test the VmInfo relevant functionality.
